. Anropet gick bra Code BlockThe 301 (Moved Permanently) status code indicates that the target resource has been assigned a new permanent URI and any future references to this resource ought to use one of the enclosed URIs. Clients with link-editing capabilities ought to automatically re-link references to the effective request URI to one or more of the new references sent by the server, where possible.

300 Multiple Choices

Code Block
 The 300 (Multiple Choices) status code indicates that the target
   resource has more than one representation, each with its own more
   specific identifier, and information about the alternatives is being
   provided so that the user (or user agent) can select a preferred
   representation by redirecting its request to one or more of those
   identifiers.  In other words, the server desires that the user agent
   engage in reactive negotiation to select the most appropriate
   representation(s) for its needs ().

Hantering av enskilda statusar

Kolumnen “Försök igen automatiskt” avser visa vid vilka HTTP-statusar det är relevant att försöka utföra samma anrop igen och förvänta sig ett lyckat resultat.

The 302 (Found) status code indicates that the target resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client ought to continue to use the effective request URI for future requests.

Permanent flyttad resurs. Byt URI som används i anropet.

The 303 (See Other) status code indicates that the server is redirecting the user agent to a different resource, as indicated by a URI in the Location header field, which is intended to provide an indirect response to the original request. A user agent can perform a retrieval request targeting that URI (a GET or HEAD request if using HTTP), which might also be redirected, and present the eventual result as an answer to the original request. Note that the new URI in the Location header field is not considered equivalent to the effective request URI.

The

414

URI

Too

Long

) status code indicates that the server is refusing to service the request because the request-target ( ) is longer than the server is willing to interpret.

Inga omförsök ska utföras.

The 417 (Expectation Failed) status code indicates that the expectation given in the request's Expect header field () could not be met by at least one of the inbound servers.

305 Use Proxy

Code Block
The 305 (Use Proxy) status code was defined in a previous version of
   this specification and is now deprecated (Appendix B).

Deprecated och används inte hos oss.

306 (Unused)

Code Block
The 306 status code was defined in a previous version of this
   specification, is no longer used, and the code is reserved.

Används inte hos oss.

307 Temporary Redirect

Code Block
The 307 (Temporary Redirect) status code indicates that the target
   resource resides temporarily under a different URI and the user agent
   MUST NOT change the request method if it performs an automatic
   redirection to that URI.  Since the redirection can change over time,
   the client ought to continue using the original effective request URI
   for future requests.

Samma som 302 med skillnaden att URI som används i anropet inte ska ändras.

400 Bad Request

Code Block
The 400 (Bad Request) status code indicates that the server cannot or
   will not process the request due to something that is perceived to be
   a client error (e.g., malformed request syntax, invalid request
   message framing, or deceptive request routing).

Inga omförsök ska utföras. 304 Not Modified

Används vid cachning. Statusen betyder att resursen inte har förändrats. Klienten kan använda den cachade versionen av resursen.

400 Bad Request

Det är något fel på anropet och det behöver korrigeras innan det är lönt att göra ett nytt anropnågon mening att försöka igen.

401 Unauthorized

✔

Nytt försök kan utföras om autentiseringsuppgifter läggs till eller uppdateras. Antingen så saknas autentiseringsuppgifter i anropet eller så tillåter inte servern åtkomst.

402 Payment Required

The 402 (Payment Required) status code is reserved for future use.

Används inte hos oss.

Reserverad status för framtida bruk.

403 Forbidden

Code Block
The 403 (Forbidden) status code indicates that the server understood
   the request but refuses to authorize it.  A server that wishes to
   make public why the request has been forbidden can describe that
   reason in the response payload (if any).
Inga omförsök ska utföras. Klienten har inte behörighet.

✔

Nytt försök kan utföras om autentiseringsuppgifter uppdateras.

404 Not Found

Code Block
The 404 (Not Found) status code indicates that the origin server did
   not find a current representation for the target resource or is not
   willing to disclose that one exists.  A 404 status code does not
   indicate whether this lack of representation is temporary or
   permanent; the 410 (Gone) status code is preferred over 404 if the
   origin server knows, presumably through some configurable means, that
   the condition is likely to be permanent.
Vanligtvis behöver inga omförsök

ibland

Vanligtvis ska inga nya försök utföras om man inte har anledning att tro att resursen kan dyka upp vid senare tillfälle. Det kan t.ex. vara lämpligt relevant med omförsök nya försök om man försöker hämta ett ärende som inte har hunnit skapas än .

405 Method Not Allowed

Code Block
The 405 (Method Not Allowed) status code indicates that the method
   received in the request-line is known by the origin server but not
   supported by the target resource.  The origin server MUST generate an
   Allow header field in a 405 response containing a list of the target
   resource's currently supported methods.

Inga omförsök ska utföras.

406 Not Acceptable

Code Block
The 406 (Not Acceptable) status code indicates that the target
   resource does not have a current representation that would be
   acceptable to the user agent, according to the proactive negotiation
   header fields received in the request (), and the server
   is unwilling to supply a default representation.

Inga omförsök ska utföras. Anropet behöver justeras.

408 Request Timeout

Code Block
The 408 (Request Timeout) status code indicates that the server did
   not receive a complete request message within the time that it was
   prepared to wait.  A server SHOULD send the "close" connection option
   () in the response, since 408 implies that
   the server has decided to close the connection rather than continue
   waiting.  If the client has an outstanding request in transit, the
   client MAY repeat that request on a new connection.

Omförsök ska utföras.

409 Conflict

Code Block
The 409 (Conflict) status code indicates that the request could not
   be completed due to a conflict with the current state of the target
   resource.  This code is used in situations where the user might be
   able to resolve the conflict and resubmit the request.  The server
   SHOULD generate a payload that includes enough information for a user
   to recognize the source of the conflict.

Inga omförsök ska utföras. men som man tror kommer skapas inom en snar framtid.

405 Method Not Allowed

406 Not Acceptable

410 Gone

code

The 410 (Gone) status code indicates that access to the target
   resource is no longer available at the origin server and that this
   condition is likely to be permanent.  If the origin server does not 
   know, or has no facility to determine, whether or not the condition
   is permanent, the status code 404 (Not Found) ought to be used
   instead.

Inga omförsök ska utföras. Resursen existerar inte längre och detta är ska vara ett permanent tillstånd.

411 Length Required

Code Block
The 411 (Length Required) status code indicates that the server
   refuses to accept the request without a defined Content-Length
   ().  The client MAY repeat the request if
   it adds a valid Content-Length header field containing the length of
   the message body in the request message.

Klienten måste lägga till headern “Content-Length” innan omförsök.

413 Payload Too Large

Code Block
The 413 (Payload Too Large) status code indicates that the server is
   refusing to process a request because the request payload is larger
   than the server is willing or able to process.  The server MAY close
   the connection to prevent the client from continuing the request.

Inga omförsök ska 412 Precondition Failed

413 Payload Too Large

Inga nya försök ska vanligtvis utföras. Storleken på anropet var för stort.

Om det är ett temporärt tillstånd så följer en header med i responsen (Retry“Retry-AfterAfter”) och då kan omförsök göras nytt försök utföras efter tiden som anges.414 URI Too Long

Code Block

415 Unsupported Media Type

code

The 415 (Unsupported

Media

Type

) status code indicates that the origin server is refusing to service the request because the payload is in a format not supported by this method on the target resource. The format problem might be due to the request's indicated Content-Type or Content-Encoding, or as a result of inspecting the data directly.

Inga omförsök ska utföras. Media Type måste ändras.

417 Expectation Failed

Code Block

417 Expectation Failed

426 Upgrade Required

code

The 426 (Upgrade Required) status code indicates that the server
   refuses to perform the request using the current protocol but might
   be willing to do so after the client upgrades to a different
   protocol.  The server MUST send an Upgrade header field in a 426
   response to indicate the required protocol(s) ().

Inga omförsök ska utföras. Protokoll som används i anropet måste ändras.

500 Internal Server Error

Code Block
The 500 (Internal Server Error) status code indicates that the server
   encountered an unexpected condition that prevented it from fulfilling
   the request.
Omförsök ska utföras.

✔

Tillståndet kan vara temporärt och t.ex. orsakas av att ett tredjepartssystem system hos tredjepart ligger nere för stundentemporärt.

501 Not Implemented

code

The 501 (Not Implemented) status code indicates that the server does
   not support the functionality required to fulfill the request.  This
   is the appropriate response when the server does not recognize the
   request method and is not capable of supporting it for any resource.

Inga omförsök ska utföras.

502 Bad Gateway

Code Block
The 502 (Bad Gateway) status code indicates that the server, while
   acting as a gateway or proxy, received an invalid response from an
   inbound server it accessed while attempting to fulfill the request.
Omförsök

✔

Nytt försök kan utföras. Tillståndet kan vara temporärt.

503 Service Unavailable

Code Block
The 503 (Service Unavailable) status code indicates that the server
   is currently unable to handle the request due to a temporary overload
   or scheduled maintenance, which will likely be alleviated after some
   delay.  The server MAY send a Retry-After header field
   () to suggest an appropriate amount of time for the
   client to wait before retrying the request.

      Note: The existence of the 503 status code does not imply that a
      server has to use it when becoming overloaded.  Some servers might
      simply refuse the connection.

Omförsök ska utföras.

✔

504 Gateway Timeout

Code Block
The 504 (Gateway Timeout) status code indicates that the server,
   while acting as a gateway or proxy, did not receive a timely response
   from an upstream server it needed to access in order to complete the
   request.
Omförsök

✔

Nytt försök kan utföras. Tillståndet kan vara temporärt.

505 HTTP Version Not Supported

code

The

505

(

HTTP

Version

Not

Supported

) status code indicates that the server does not support, or refuses to support, the major version of HTTP that was used in the request message. The server is indicating that it is unable or unwilling to complete the request using the same major version as the client, as described in , other than with this error message. The server SHOULD generate a representation for the 505 response that describes why that version is not supported and what other protocols are supported by that server.

Inga omförsök ska utföras.
